About this study
Official title: Treatment Failure and Associated Predictors Following Azithromycin Treatment for Urogenital Chlamydial Infection in Males in Youth Correctional Facilities
The proposed study is a single center (with multiple long-term YCFs) treatment trial of the CDC-recommended azithromycin regimen (1 gm PO once) for chlamydia in males. This study is designed primarily to determine the frequency of chlamydia treatment failure following azithromycin in males who do versus do not have urethral symptoms of urethral discharge and/or dysuria. Anticipated enrollment is 446 males, between the age of 12 to 21 years old, with subject participation duration of 28 days and study duration of 4 years. The primary objective of the study is to assess the microbiological efficacy of azithromycin in uncomplicated Chlamydia trachomatis infection in males with versus without urethral symptoms in YCFs.
Read the detailed description
The proposed study is a single center (with multiple long-term YCFs) treatment trial of the CDC-recommended azithromycin regimen (1 gm PO once) for chlamydia in males residing in long-term gender-segregated YCFs. This study is designed primarily to determine the frequency of chlamydia treatment failure following azithromycin in males who do versus do not have urethral symptoms of urethral discharge and/or dysuria. Males age 12 to 21 years in good health (based on vital signs and provider's clinical evaluation documented in medical records) who are residing in long-term gender-segregated (not co-ed) YCFs (usual stay > 3 weeks) and who are identified as chlamydia-infected comprise the study population. The anticipated enrollment is 446 males with subject participation duration of 28 days and study duration of 4 years. The primary objective of the study is to assess the microbiological efficacy of azithromycin in uncomplicated Chlamydia trachomatis infection in males with versus without urethral symptoms in YCFs; in essence, this study will assess the frequency of chlamydia treatment failure to azithromycin at the Day 28 follow-up visit (Visit 2) in males with urethral symptoms compared to males without urethral symptoms. The secondary objective is to evaluate the association of laboratory findings (enrollment chlamydia load and OmpA genotype) and other participant characteristics (demographics, sexual behaviors, etc.) to chlamydia treatment failure in males after azithromycin treatment.

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Participants Experiencing Treatment Failure After Treatment With Azithromycin for Uncomplicated Chlamydia Trachomatis (CT) in Males With and Without Urethral Symptoms
Test positive for Chlamydia trachomatis with Aptima Combo 2® Assay (AC2) and having enrollment and follow-up CT strains that had concordant genotyping of the CT major outer membrane protein (ompA) sequences or, if genotyping was unsuccessful on urine from both visits (i.e., due to insufficient number of ompA copies), then participants could not have unsupervised furloughs or report interim sex to be categorized as a treatment failure.
Measured: Day 28-follow-up visit
Secondary outcomes (1)
Evaluate the Association of Laboratory Findings and Other Participant Characteristics to Chlamydia Treatment Failure in Males After Azithromycin Treatment
Odds ratios for the outcome of treatment failure calculated for laboratory findings (enrollment chlamydia load and OmpA genotype) and other participant characteristics (demographics, sexual behaviors, etc.). Note that samples were not run for OmpA genotype.
Measured: Day 28-follow-up visit

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Oct 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Participants Experiencing Treatment Failure After Treatment With Azithromycin for Uncomplicated Chlamydia Trachomatis (CT) in Males With and Without Urethral Symptoms (time frame: Day 28-follow-up visit). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2019.
